over the last few days i have been thinking a little bit about the cat rfid projects. the doorbell project looks like it might turn into the rfid cat window entrance. but why do the cats get a fancy new way to come and go. humans like technology too. so i think there will be a human rfid auto door unlocker. you just walk up and turn the door knob and it will only be unlocked for those authorized.
with cats it is easy. they have a collar. but where to place one on a human? my first thought was to use some of the same material as the birth control patches (minus hormones of course) . then i saw this...
